"Radio Shack fixed my Indiana Jones Path of Adventure for $2.99!!", or "Radio Shack is good for more than just the $9.99 desoldering iron"! Problem: William's Indiana Jones has a "Path of Adventure" (POA), which is a mini playfield that the user can move left or right with the flipper buttons during game play to control the ball. Unfortunately, the motor tends to die making the POA fail. Solution: Replace the POA motor. This will fix most POA problems, but not all. Also you should check the two optos that determine right and left movement of the POA. Also there is a motor control PCB underneath the playfield which can also go bad. For this article we will assume the following: - the POA motor control PCB is working. - the POA gearbox is in good condition. - you have CPU software version L-7 (important!) - the POA motor itself is bad. Parts needed: - Radio Shack "High-Speed 12VDC Motor", part number 273-255, $2.99. They also sell a "High-Speed 9-18VDC Motor", part number 273-256, $3.49. You can use this motor, but really I would recommend the 12vdc motor, #273-255 (the 9-18vdc motor turns a little faster). If all they have is the 9-18vdc motor, buy it as it will work. but again, I recommend getting the right motor (#273-255). To determine if the motor is bad, turn the game off and remove the playfield glass. Pull the playfield all the way forward, resting it on the metal rails attached under the playfield. This should give about twelve inches in back of the playfield to work. The motor attaches to the gearbox behind the playfield with two machine screws. Remove these screws, and the motor will pull out. Examine the gear on the end of the motor. It should be in good condition. If not, you'll have to contact a Williams parts supplier and get a new gearbox and motor. Remove the six balls from the game, and lift the playfield up into the vertical position. The motor should be visible at the bottom of the cabinet, dangling by the two wires attaching it to the motor control PCB. Turn the game on. The game power-on should start the motor; first to the left and then to the right. If the motor does not move, chances are it's bad (or the motor control PCB is bad). Most often the motor windings inside break due to stress. After taking apart my motor that was pretty obvious. Turn the game off and remove the motor by disconnecting the molex connector from the motor control PCB. Go to Radio Shack and buy part number 273-255, "High Speed 12vdc Motor" for $2.99. There is a mounting plate attached to the old motor with two screws. Remove the screws and this plate. Attach the plate to the new motor. There are already holes in the right place on the new motor. And the screws will fit perfectly. Remove the old gear from the original POA motor. It is pressed fit, and pulls off with gentle persausion. Note the original motor has a toothed shaft. Unfortunately the Radio Shack motor has a smooth shaft. I used some double sided tape wrapped around the Radio Shack shaft, and pressed the old gear on the new motor. This worked fine. But the tighter the fit, the better. Remove the red and white wires from the old motor, and solder them to the new motor. Don't worry about which wire goes where right now. Just solder them both on (you have a 50% chance of getting it right!). Attach the new motor to the motor control PCB with the molex plug. Do not attach the motor to the gearbox just yet. Now turn the game on. The dangling motor should immediately spin left and then right. If it does not, there is a problem with the motor control PCB. Turn the game off and fix this board. If the new motor does spin left then right, the new motor has fixed your POA problems. At this point you may want to remove the POA. If you have the time, I would recommend this (if you haven't done it already). To remove the POA, you need to remove the bridge across the back of the game, the habit trail and the stainless steel path along side the POA, and finally the stainless steel "funnel" going to the habit trail. The POA attaches with two screws and pulls out towards the coin door. With the POA removed, testing the motor and gearbox is easy and there's NO chance of damaging anything if the wires are reversed to the motor. Also fixing the optos (if needed) is easy with the POA removed. Check the optos to make sure they are working. You must do this with the motor removed from the gearbox. Put the game in Test POA diagnostics. Then move the POA by hand. Switches 94 and 95 should be activated as the POA claw moves between the optos. If one of the optos does not register, replace it. You have two built-in spares already in your game; the flipper switch board uses the same optos, two per side. But only one is used for each flipper. You can remove one spare from each side and use that as the replacement. Make sure you remove the correct opto from the flipper boards!! Use a business card between the optos with the game in diagnostics to determine which opto you can remove. Now you are ready to install the new motor to the gearbox. Move the POA by hand so it is level. If the POA is removed, position the claw half way between the two optos. Re-attach the motor to the POA gearbox at the back of the playfield. Turn the game back on. The POA should move left then right. If the POA is removed, you will see the "claw" move down and then up between the optos. If the POA is installed and you hear ANY grinding, immediately turn the game off. Grinding might occur if the wires were soldered to the motor in reverse position. If the POA is removed, this is not a worry (and hence is a good reason to remove the POA in the first place). If the claw moves up and then down, you have the wires reversed. Remove the motor and reverse the white and red wires at the motor, and reinstall. With the motor installed and the wires attached correctly, go into diagnostics, Test section, POA test. The POA will immediately be tested. If all is good, you will receive a message saying the POA tested successfully. Press advance and go into the POA test. Use the volume buttons to move the POA left and right (or the claw down and up if the POA is removed). Make sure the screen left/right movement identification matches the actual left/right POA movement. Installation is now complete for the new POA motor on Indy Jones! If you removed the POA, now re-install it (after you clean the jet bumper area under the POA).
